Power optical network fault root cause positioning method and system based on business correlation analysis
By using a business association analysis approach, combined with multivariate Hawkes process modeling and condition dependency testing, an alarm causal relationship for power optical communication networks is constructed, solving the problem of inaccurate fault location in existing technologies and achieving high-precision fault source location in complex network environments.

Abstract
本发明公开了基于业务关联分析的电力光网故障根因定位方法及系统，包括如下步骤：采集网络中的告警信息、业务承载信息、链路连接关系及网络拓扑信息，进行标准化处理，形成告警事件序列及业务承载关联数据；基于业务承载关系与网络拓扑构建业务、链路与设备之间的关联结构，确定告警事件对应的业务路径、链路路径及设备位置，生成候选关联集合；对告警事件之间的时间触发关系进行多元Hawkes过程建模，得到初始告警关联结构；结合业务路径和链路路径，对告警关联关系进行条件依赖检验，生成稀疏因果关系结构；根据告警触发方向及发生时间，识别级联传播起始节点，形成故障根因候选集合，并输出故障定位结果。本发明涉及通信网络管理技术领域。
